I had a split pane which is divided into four panes. These panes are divided horizontally. The third pane contains a question and answer field. The user will press a Next button after entering the answer. When the user presses the next button the whole pane should not be disposed only the question and answer in the third pane should be erased and new question and answer field should appear in that pane. How can we do this? How can we get a particular pane from a split pane?
